The purpose of this study is to investigate the safety and effectiveness of trigeminal nerve electrical stimulator on reducing the frequency of migraine onset. It is applied to migraine patients and analyzes the results by comparing them before and after 4weeks.

• Duration of study period (per participant): Screening period (-6~0weeks), Intervention period (4weeks).
• Patient needs to visit site at least 3 times (Screening, Baseline, V4), V2 can be done with screening visit. V3 is tele-Visit.
• The clinical trial device performs a personal electrical stimulation around the trigeminal nerves for 4weeks (6 times/week), 20 minutes each time.
• During the study period, examination and treatment methods are carried out in the same way.

Inclusion Criteria:

• Men and women over 19 years old
• Patients with migraine with or without migraine aura who meet ICHD-III (2018) diagnostic criteria 1.1 1.2

• Patients with mental illness who can interfere with their participation in the study.
• In the case where medical devices for clinical trials cannot be applied due to being sensitive to orbital nerve stimulation.
• Patients with a history of drug or alcohol abuse
